Neither snow nor rain nor gloom of night will stop the mail, but $15.9 billion in losses will, at least on Saturday. The U.S. Postal Service is expected to announce today that it will suspend Saturday mail delivery starting August 1. Packages will still be delivered on Saturday, which is a profitable part of the business, and post offices will remain open on Saturdays so customers can drop off their mail, buy stamps, and check their post-office boxes—although open hours are likely to be reduced. Suspending Saturday mail delivery is expected to save the USPS $2 billion annually, much-needed savings as the postal service said it has lost $15.9 billion in the last fiscal year—three times the loss recorded just a year earlier.
